I've yet to play around with it yet, but Antonio Lirio was nice enough to add captions to his previous tutorial which is a giant help to me. You can see that video above.
Also, YOSHIOKA Ume on the Adobe Forums created an AIR Utility that will take a JSON sprite sheet and output a format compatible with Edge Animate. The problem is you have very limited control over the timeline of it. Mainly, you can't vary the amount of time held on each frame.
Either way, big thanks for creating it: Sprite Sheet Converter
So I haven't tried either yet, but plan to very soon. The game plan is to put something up as the header of this blog and then try something more complex with the RBMC blog. I'm hoping to have results soon.
